Get him tested! Not everyone gets a bulls eye rash. My son had it last summer and it started with an achey shoulder, he id get a very high fever but he also had cellulitis so his high fever was probably having 2 infections at the same time. Lyme disease is nothing to mess around with. My best friend had it it went untreated for along time now she is 30 and can barely get out of bed in the morning because her arthritis is so bad. I'm kind of shocked that the er didn't test the tick. My pedi says to take the tick into the office and it can be tested instead of taking a blood test.
